Example application showing FreeMASTER Serial Communication usage
The purpose of this demo application is to show you how to use the FreeMASTER serial communication using S32K148 on OpenSDA with this SDK.
This demo uses the FreeMASTER Run-Time Debugging Tool to visualise ADC conversions and allows the user to monitor the ADC sampling rate for different ADC configurations (ADC sampling time and resolution can be controlled through FreeMASTER Application Commands).
The ADC is configured to perform continous conversions and generate an interrupt after each conversion. The LPTMR is configured to generate a periodic interrupt at 10 ms which reads the number of ADC conversions.
The run the example you will need to have the following items:
The following boards are supported by this application:
The following connections must be done to for this example application to work:
PIN FUNCTION | S32K148EVB-Q100 | S32K148-MB |
---|---|---|
LPUART1 TX (PTC7) | UART_TX - wired on the board | J11.26 - J20.2 |
LPUART1 RX (PTC6) | UART_RX - wired on the board | J11.25 - J20.5 |
ADC0 Input 12 (PTC14) | POT - wired on the board | J21.1 - J11.18 |
After opening S32 Design Studio, go to File -> New S32DS Project From... and select freemaster_s32k148. Then click on Finish.
The project should now be copied into you current workspace.
First go to Project Explorer View in S32 DS and select the current project(freemaster_s32k148). Then go to Project and click on Generate Processor Expert Code
Wait for the code generation to be completed before continuing to the next step.
Select the configuration to be built FLASH (Debug_FLASH) or RAM (Debug_RAM) by left clicking on the downward arrow corresponding to the build button(. Wait for the build action to be completed before continuing to the next step.
Go to Run and select Debug Configurations. There will be four debug configurations for this project:
Configuration Name | Description |
---|---|
freemaster_s32k148 Debug_RAM Jlink | Debug the RAM configuration using Segger Jlink debuggers |
freemaster_s32k148 Debug_FLASH Jlink | Debug the FLASH configuration using Segger Jlink debuggers |
freemaster_s32k148 Debug_RAM PEMicro | Debug the RAM configuration using PEMicro debuggers |
freemaster_s32k148 Debug_FLASH PEMicro | Debug the FLASH configuration using PEMicro debuggers |
Select the desired debug configuration and click on Launch. Now the perspective will change to the Debug Perspective.
Use the controls to control the program flow.
FreeMASTER host application can be downloaded from NXP's website. FreeMASTER Serial Communication is included into the project (V2.0).
